      What are the parts of a computer? (article) | Khan Academy (5)

      for pictures and videos lets break it down into an individual pixel, the entire color spectrum consists of 3 primary colors, red green and blue, so a certain amount of red green and blue can make any color visible to the naked eye, pixels use numbers to figure out how much of each primary color it needs to display to get the right color, anywhere from 0-255, for example 255 red, 0 green and 0 blue will give you the color red, 255R 255G 255B will give you black, assuming you know how binary numbers work, its simply taking binary numbers(bits) and turning them into numbers for each primary color and then the pixel does what each of those primary color numbers say, apply some very complex wiring and you have a a computer screen like the ones you are using to read this, for sound its a bit more complicated but its the same concept, every single sound has a unique frequency, these frequencies can be graphed using numbers, so heres where the same concept applies, the computer can get those numbers using binary as well, and then it sends an electrical current with the same frequency that the binary code(bits) requested, and the speaker turns that into sound

      It sounds like you're interested in programming. We have many courses here: https://www.khanacademy.org/computing/computer-programming

      There are also lots of other ways to learn coding online, like Codecademy, Scratch, Repl.it, etc. The key to programming is to practice, practice, practice!

      Well, one of the most important components in a computer is the CPU. CPU stands for Central Processing Unit. This could be thought of as the main "hub."

      All pictures are made up of pixels.
      If you can see them that means that you're looking at a picture which as fewer pixels.
      The more pixels a picture has the smaller the pixels get (or seem?). So high quality pictures have a lot more pixels over a given area than low quality images and consequently seem smoother, because they're so small you can't see them.
